'DEVICE TO OPEN RAILWAY-CAR 'VENTILATORS.

The Schedule-referred to in these Letten Patent and malnng part` of the sme.

To all 'whom it may concimi Be it known that we. W. G. S'rronNnr and J. Me- GEE, of Steubenville, in thc county ofJeiierson, and State of Ohio, have invented .a new and improved Ventilator-Opener for Cars, 85e.; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, refercncebeng had to the 4accompanying drawings, forming part of this specification, -in which- Figures 1 and 2 are vertical vsections of a car-ventilator, to which ourimproved opener has been attached.

Similar `letters of reference indicate ,coiresponding parts.

' O nr invention has for its object to furnish an in1- proved device, by means of which the pivoted sash, shutter, or valv'e of the ventilator, may be opened, closed, or secured at any desired angle, conveniently and securely; and l It consists in the construction and combination of the-various parts of the opener, as'hereinafter more fully described.

A represents the body of the car.

B vrepresents the sash, shutter, or valve ofthe ven-v tilator, which is pivoted to the frame or body A, in the ordinary manner. o

C is an arm or standard, which is securely attached to the sash B, upon or near the line of its pivots.

The -T, or cross-head' dl, of the sliding rod D, iis slotted, and is securely attached to the end of the rodfD, and upon the other end of said rod is formed, or to it is attached a knob or handle, d2, for convenience in opening our-'device The upper end of the rod D is pivoted to the outer or free end of the arm or standard 0, by a pivotingpin and slot, said slot being founed either in the said outer or free endV of the armor standard O, or Vinthe upper end ofthe rod D, or inv the T, or cross-head d', ofthe sliding,r rod 1), as showlrin gs. 1 and 2.

'.lhe rod l) passes through and slides longitudinally in the thimble E, the standards or shank e of which is secured to the frame A.

By this construction, the sash -B may be opened or closed fully, or t'o anydcsired angle, by simply oper ating the sliding rod D. v

In the case of ears, or where the device is subject to constant wear, it is necessary that the rod D should be secured, so that it may not work or slip downward, and thus close'the ventilator.

'lo prevent this, the standard or shank e, of the thimble E, is made hollow, and in the recess thus' formed is placed a coiled-wire spring, F, and a friction-block, G, or their equivalent, which said block G is forced against the -rod D by the elasticity of the spring F, so as `to hold the said rod secnrelyin any position in which it mayv hc placed.

y Having thus described our invention,

' We cla-iin as new,oand desire to secure by Letters Patent- The thinxble E, hollow shank e, spling F, and frie-v tion-block G, and the vertically-sliding rod D, having the slotted T-head fl, in combination with the pivoted sash B, and frame A, arranged and operating as described for the purpose specified.
